WAVE-MOTOR.

Specification of Letters Patent.

Patented J uly 29,1913.

Application filed March 21, 1912. Serial No. 685,220.

To all whom 1' t may concern lle it known that I, Cant. E. BENSON, acitizen of the United States. 'residing at San Francisco, in the countyof San Francisco, State of Californ-ia, have invented certain new anduseful Improvements in lVave- Motors; and I do hereby declare thefollowing to lbe a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to improvements in wave motors, and particularlytothe type of non-pivoted floats.

-Thelprincipal object of the invention is to provide an eti'ective andsimple construction whereby the greatest amount ofv wave power may beconcentratedatcertain points.

Other objects reside in the peculiar construction and arrangement of thevarious parts. I

In the drawingsz'Figure 1 is an elevation of one of my wave motors,partly in section, Fig. 2 is a horizontal section on the `line 2 2 ofFig. 1, Fig. 3, isa plan view,

showing the position of my device with respect to the shore and theocean, Fig. 4. is a vertical section on the line 4-1 of Fig. 1 loc-kingin the direction of the'arrow.

Referring particularly to the dra-wings, 1Q represents a concretestructure which is built on the shore, extending down a distance intothe ground as a` foundation and.

extending a'suitable distance up in `the air in the form of a tower.This concrete structure is hollow and has one side 11 opened. This sidebeing toward the ocean, and extending divergently outward from the saidconcrete structure of the series of piles 12, to which are securedmaterial of any suitable description to form a breakwater guide 13 sothat the waves will be guided to Ithe open side`11 of the concreteversely'extended shafts lt'and 17. Keyed on these shafts are sprocketwheels 18 and 18. Loosely mounted on the shaft 17 is a rotatable memberincluding a ratchet por-" tion 19, and a pinion portion 20. The ratchetportion bearsagainst the sprocket wheel 18, and is adapted to be engagedby a springr pressed pawlx21 secured on the adjacent face of saidsprocket. Mounted ou the shaft 1G is a similar rotary member in- 'doublerack bar 32, having the rack teeth .ad and 34 on its respective sides,the former 'of which meshes with the pinion portion 20 and the latter ofwhich meshes with the pinion portion 23. Mount-ed on'the ,lower end ofthe rack bar is a suitable hollow buoyant body 8?/ which is adapted tobe acted upon by the waves. Extending vertically on the sides ottheconcrete structure are the `guide rails 'on which the said buoyantbody ,is adapted to slide .vertically and be guided positively uplanddown the interior ofthe concrete structure. rl`he buoyant body 33 istransversely concaved on its under side of the forward portion, saidconcavity beginning at the front of the body 33 and ineliningdownwardtoward the back of the body. Thisl portion of the buoyant body ispresented toward the ocean, and facilitates the entry of a` wavetherebeneath, so that the4 same lnaybe easily raised. It will thus beseen that the waves will be guided between the wall. 13 and concentratedat. the bottom of a concrete structure, and raise the buoyant body BIVwhich pushes the rack bar 32 upwardly. The teeth will rotate the piuionportion 2O and cause the sprocket wheel 1S to rotate and communicatemotion to the shaft 26. 'lhe ratchet wheel will rotate idly under itspawl. Upon the receding of the, waves the float or buoyantI body 2323will fall. The teeth on the opposite side of the drop androtate-thefshaft '16. f
